Over 25 years of IT consulting expertise for small & medium businesses and consulting firms across Europe. We engineer data infrastructure that actually works.
These are the most common data and IT challenges we hear from SMBs and consulting firms. If any of these sound familiar, we should talk.
01 —
Data you can't trust
Reports built on ad-hoc queries, spreadsheets, and undocumented transformations. No single source of truth. Every dashboard tells a different story — and no one knows which one is right.
02 —
Pipelines that break silently
Fragile data pipelines built as cron jobs or manual scripts — with no monitoring, no alerting, and no documentation. You find out something failed when a stakeholder notices wrong numbers.
03 —
No clear data architecture
Data scattered across multiple systems with no consistent structure. New requirements take weeks to implement because the foundation wasn't designed to scale. Technical debt compounds with every release.
04 —
IT complexity without the team to manage it
Growing businesses need enterprise-grade data infrastructure but don't have a full in-house data engineering team. Hiring is slow and expensive — and the technology keeps evolving.
Our Approach
How We Work
A clear four-step process from first conversation to production-ready delivery. No ambiguity, no surprises — just structured engineering.
Step 01
Discovery
We start by understanding your business context, data sources, reporting needs, and existing infrastructure — before writing a single line of code.
Step 02
Architecture
We design the right solution: medallion layers, star schema, orchestration strategy, and technology choices — documented and agreed before build begins.
Step 03
Build & Test
We implement dbt models, Airflow DAGs, and PostgreSQL structures with full test coverage, documentation, and iterative reviews with your team.
Step 04
Handover
We deliver production-ready systems your team can own and maintain — with full documentation, knowledge transfer, and optional ongoing support.

Who We Are
Your Data, Our Expertise
Magic Byte is a Brussels-based IT consulting firm specialising in data engineering, ELT pipeline architecture, and data modeling for small and medium businesses and consulting organisations across Europe.
With over 25 years of hands-on experience, we design and implement robust, scalable data infrastructure — from raw ingestion through to analytics-ready gold-layer models — that empowers your teams to make confident, data-driven decisions.
25 years in the field. Countless pipelines shipped. One mission: making enterprise-grade data engineering accessible to the businesses that need it most.
